- -----------------------------------------------------------

YOUNGSTOWN, OHIO-- Mahoning National Bancorp, Inc. (Nasdaq: "MGNB" ) announced
today that its shareholders have approved the merger with Sky Financial Group,

completion of the merger with Mahoning, the Sky Financial Group will have
approximately $7.7 billion in total assets, $5.8 billion in total deposits and
$585 million in total shareholder's equity, with 223 banking centers throughout
Ohio, western Pennsylvania, West Virginia, Michigan and Indiana.

Under the agreement, Mahoning shareholders will receive 1.66 shares of Sky
Financial common stock for each share of Mahoning common stock in a tax-free
exchange.

Mahoning National Bancorp, Inc., with headquarters in Youngstown, Ohio, and
assets of approximately $825 million, is the parent of Mahoning National Bank of
Youngstown, a full service bank also providing trust and financial services.
